Theldus / vlc_recent_files.patch

Created October 20, 2020 17:38

Increase maximum recent files on VLC

	# Increase maximum recent files on VLC, by Theldus
	#
	# First of all, this is not an official patch!, apply at your
	# own risk, nonetheless, it should be safe =).
	#
	# Second of all, it's so much easy to increase this limit, why on earth VLC
	# uses a hardcoded number? 10 at the moment. VLC already saves more than 10
	# items on the ~/.config/vlc/vlc-qt-interface.conf, so why not makes use of
	# such thing? I really dont know. Anyway, apply this and be happy.
